Filed provides AI-powered tax preparation software that automates the complete lifecycle of a tax return for accounting professionals. Its Tax Preparation module reads source documents and populates returns, its Reviewer cross-checks figures against sources to catch errors before sign-off, and its Tax Planner evaluates 120+ strategies backed by actual return data. The platform escalates ambiguous scenarios for human review and is SOC 2 Type II certified and IRS 7216 compliant. Founded by Leroy Kerry, Filed raised a $17.2M pre-seed/seed round backed by Northzone, Day One Ventures, J Ventures, Neo, Raine and Greens Ventures to help firms expand capacity without adding headcount.
